A battery pack securing mechanism for securing battery packs of varaying numbers of battery cells, a battery charger capable of charging the battery packs or an electronic equipment capable of using the battery packs. In a battery pack having the optional number of cells built therein, this terminal is provided in the same position as a terminal position wherein only one cell is accommodated within the battery pack. A charger and an electronic equipment using a pack have a pack securing section capable of securing battery a pack having at least two cells accommodating therein in parallel, and includes an engaging member for engaging at least one cell pack with the battery pack securing section and a connecting member connected to the positive and negative electrode terminals of the one cell pack and disposed at such a position that charging or discharging can be performed. Accordingly battery, packs accommodating different number of cells and of various arrangements and configurations can be used.
